Why is my Fujitsu Compact Wall Mounted Type not cooling or heating properly?

Several factors can impact the cooling or heating performance of your Fujitsu Air Conditioner. Check if the air filter is dirty or if the intake grille or outlet port is blocked. Ensure the thermostat is set correctly and that no windows or doors are open. For cooling, close curtains to block direct sunlight and reduce heat-generating appliances or the number of people in the room. Also, verify that the unit is not set to SUPER QUIET operation.
